2.3.5 Flexible Numbering/Fixed Numbering
Description
To dial another extension user or to access PBX features, the access numbers (extension
numbers or feature numbers) are required.
There are three types of numbering plans:
1) Flexible Numbering (available while a dial tone is heard)
2) Flexible Numbering (available while busy, DND, or ringback tone is heard)
3) Fixed Numbering (available while dialling or talking)
1. Flexible Numbering (available while a dial tone is heard)
Extension numbers and feature numbers which are available while a dial tone is heard can
be customised for easy use ( Flexible Numbering [100]). The numbers must not conflict.
It is also possible to use default (Pattern 1 or Pattern 2) shown in the following table:
a) Extension Numbers (Extension Numbering Scheme 1 through 32): Up to four-
digit number (up to two-digit leading number consisting of "0 through 9" ) + additional
digits (up to two digits, default: two digits)
[Example]
If the number "3" as a leading number for the 1st extension numbering scheme and
the "2" as an additional digit have been programmed, the extension number 300
through 399 are available.
b) Feature Numbers: Up to four-digit number consisting of "0 through 9", " ", and "#"
c) Other PBX Extension Numbers (Other PBX Extension Number [TIE] -1 through
16): Up to three-digit number consisting of "0 through 9", " ", and "#"
